The most disadvantaged Americans are poised to get hit the hardest by Trump's trade war

Washington and Beijing have placed duties on hundreds of billions of dollars' worth of each other's products.

The effects of protectionist policies tend to be unevenly felt by Americans.

Economists say tariffs could most affect those who can least bear the burden of increased prices and retaliatory actions.

If President Donald Trump follows through with threats to escalate protectionist policies against China, consumers across the country are bound to notice higher prices and more difficult business conditions. But economists say negative effects won't be evenly felt.

The two largest economies have so far targeted hundreds of billions of dollars' worth of each other's products. And as the Trump administration continues to try to pressure Beijing to change policies seen as unfair, it has prepared duties on another $267 billion worth of Chinese products.

Mill products: flours including those form wheat, corn, buckwheat, rice, rye, other cereals, potatoes, and bananas; groats and meal of various types including wheat, corn, oats, and rice; malt; starches of wheat, corn, potato, and more

"People who shop at Walmart or Target are going to be hit harder than people who buy their toaster ovens from Williams Sonoma or can afford to get products from a higher-income country," said Mary Lovely, an economist at Syracuse University who specializes in trade with China.

US officials initially sought to minimize effects on consumers, but that becomes increasingly difficult with each round of targeted products. A majority of items in the next tranche, which would effectively target every import from China, would most likely be finished goods like clothing and electronics.

Importers can absorb the cost, pass it on to consumers, or change products altogether. For businesses operating at a slim margin, paying import taxes of 10% to 25% isn't an option. This can easily translate to higher prices for Americans who can least afford them, Lovely said.

"We have a very unequal distribution of the burden that is being felt by Americans as a result of the tariffs," she noted. "It's going to act just like a regressive tax."

The same could follow for those most affected by retaliatory actions against the Trump administration. China has responded with duties on about 85% of American products it imported last year, including dozens of key agricultural items.

In September, the administration began distributing bailout checks to farmers who were poised to suffer financial losses from its policies. The tariffs come at a time of rising challenges for the industry, where bankruptcies have been on the rise.

China's Xi Jinping and Trump are expected to meet in Argentina on Saturday, where the framework of a deal to defuse tensions could be on the table. But Washington has given conflicting signals on negotiations with Beijing in recent days.

One thing seems all but certain, however: another round of tariffs would be met with widespread opposition. The New York Times reported Tuesday that Trump is concerned about what impact his trade war could have on the performance of the stock market and the economy.

"I think that’s one of the reasons the Trump administration and the president himself have not talked recently about [additional tariffs]," said Nicholas Lardy, an expert on China at the Peterson Institute for International Economics. "A few months ago, he talked constantly about that. More recently, the frequency of threats to do this has declined dramatically."
